Python简单读写-边读边写

import os


def traverse(f):
    with open('D:/morefuncode.txt', 'a', encoding='UTF-8') as h:
        fs = os.listdir(f)
        for f1 in fs:
            tmp_path = os.path.join(f, f1)
            if not os.path.isdir(tmp_path):
                with open(tmp_path, 'r', encoding='UTF-8') as g:
                    fa = g.readlines()
                    h.writelines(fa)
                    h.write('\n')
            else:
                 traverse(tmp_path)
path = 'D:/morefun-android/app/src/main/java/com'
traverse(path)

遍历文价夹下所有文件，写到一个文件中。Python代码量是真真真真少啊！
